Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Brachycentrus appalachia (Apple Caddis) Caddisfly Adult Pictures

The wings of this specimen were pale tan, almost white, when I collected it, and the body was of the lighter "apple green" from which this species gets its common name. Everything turned much darker by the time I got it home and under the camera.

The wings look even darker in some of these pictures because the background is black and the wings are unusually translucent. You can see that in one of the pictures where the body easily through the wings. They're really a light, translucent gray, which is still far from the pale tan of the same fly when it was freshly emerged.
